LOCATION REQUIREMENTS AND CONSIDERATIONS
WARNING
IT IS NOT DESIRABLE TO INSTALL A GAS FIRED WATER HEATER IN A
RESIDENTIAL GARAGE. IF INSTALLATION IN A RESIDENTIAL GARAGE IS
YOUR ONLY OPTION, THIS WATER HEATER MUST BE INSTALLED SUCH
THAT THE PILOT FLAME AND MAIN BURNER FLAME ARE NO LESS THAN
18 INCHES ABOVE THE FLOOR (SEE FIGURE 2 BELOW). THIS IS TO
REDUCE BUT NOT ELIMINATE THE RISK OF IGNITING FLAMMABLE
VAPORS WHICH MAY BE PRESENT IN A GARAGE. THE WATER HEATER
MUST BE LOCATED OR PROTECTED TO AVOID PHYSICAL DAMAGE
BY VEHICLES OR FLOODING. FAILURE TO FOLLOW THESE
WARNINGS CAN CAUSE A FIRE OR EXPLOSION, RESULTING IN
PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
SITE LOCATION
1.
Select a location near the center of the water piping system. It must
be installed indoors and in a vertical position on a level surface. DO
NOT install in bathrooms, bedrooms or any occupied room normally
kept closed.
2.
Locate the water heater as close to the chimney or gas vent as is
practical. Consider the vent system piping and combustion air supply
requirements when selecting the water heater location. The venting
system must be able to run from the water heater to the termination
with a minimal length and elbows. THE VENT PIPE CANNOT
EXCEED THE MAXIMUM ALLOWABLE LENGTH OF 40 FEET WITH
3 LONG RADIUS ELLS.
3. Locate the water heater near the existing gas piping. If installing a new
gas line, locate the water heater to minimize the pipe length and
elbows.
IMPORTANT
4. The water heater should be located in an area where leakage of the
tank or connections will not result in damage to the area adjacent to
the water heater or to lower floors of the structure. It is recommended
that a suitable drain pan be installed under the water heater as shown
above. This pan is to protect the property from damage which may
occur from normal condensate formation on the tank jacket or leaks in
the tank and pipe connections. The pan must limit the water level to a
maximum depth of 1 3/4 inches and be two inches wider than the
heater and piped to an adequate drain. Locate the water heater near a
suitable inside drain. Outside drains are subject to freezing
temperatures. The piping should be at least 3/4” ID and pitched for
proper drainage. This pan must not restrict combustion air flow.
UNDER NO CIRCUMSTANCES IS THE MANUFACTURER TO BE
HELD LIABLE FOR ANY WATER DAMAGE IN CONNECTION WITH
THIS WATER HEATER.
5.
The water heater should be located in an area not subject to freezing
temperatures. Water heaters located in unconditioned areas (i.e. attics,
basements, etc.) may require the insulation of the water piping and drain
piping to protect against freezing. The drain and controls must be easily
accessible for operation and service.
Maintain proper clearances as specified.
6.
Do not locate the water heater near an air-
moving device. The operation of air-moving
devices such as exhaust fans, ventilation
systems, clothes dryers, fireplaces, etc.,
can affect the proper operation of the
water heater. Special attention must be
given to conditions these devices may
create to avoid unsatisfactory operation
of the equipment.
CLEARANCE/ACCESSIBILITY
Minimum clearances from combustible materials are stated on the data plate
adjacent to the thermostat of the water heater. REFER TO THE DATA
PLATE OF THE WATER HEATER FOR THE CORRECT CLEARANCES
FROM COMBUSTIBLE CONSTRUCTION MATERIALS. Figure 3 may be
used as a reference guide to locate the specific clearance locations. A
minimum of 24 inches of front clearance should be provided for inspection and
service.
WARNING
THE WATER HEATER IS CERTIFIED FOR INSTALLATION ON A
COMBUSTIBLE FLOOR. HOWEVER, WHEN THIS WATER HEATER IS
INSTALLED OVER CARPETING, THE CARPETING MUST BE PROTECTED
BY A METAL OR WOOD PANEL BENEATH THE WATER HEATER AND
EXTENDING BEYOND THE FULL WIDTH AND DEPTH OF THE WATER
HEATER BY AT LEAST THREE INCHES IN ANY DIRECTION. IF THE
WATER HEATER IS INSTALLED IN A CARPETED ALCOVE OR CLOSET,
THE ENTIRE FLOOR MUST BE COVERED BY THE PANEL. FAILURE TO
FOLLOW THESE INSTRUCTIONS MAY RESULT IN A FIRE HAZARD.
